The Lowdown
Alright folks, Rusty here. Let's take a look at what's on the menu for Kennebunk Beach. I gotta be straight with you – this is a tough stretch for us. The forecast is a long, dry spell with basically nothing worth paddling out for.
Looking at the whole 16-day run, the outlook is pretty bleak. We’ve got a gap right from the start that goes all the way through. There are no good surf options on offer here. For day after day, the wave energy is weak, mostly showing values in the low teens to under 100 (weak energy), and the wave comment keeps saying "poor surf conditions." The swell is tiny, mostly from the SE or SSE, and the wind is nearly always cross-on or onshore, messing up what little bump there is.
The water temp is sitting at 65.3°, which is about average for the time of year, but you won't be worrying about that because you won't be surfing.
Even when we get into the second week, things don't really improve. There are a couple of moments where the swell gets a bit bigger. On Monday, August 17th, the afternoon shows a 4.6ft swell from the S, with combined energy hitting 132 (moderate wave energy), but the period is a short 5 seconds and it's a cross-shore wind. Then on Sunday, August 23rd, the afternoon shows a 5.2ft S swell with energy up at 237 (moderate wave energy), but again, it's a short 5-second period and a moderate cross-shore wind. That's too small and messy to call a standout, and the surf quality is still listed as poor.
We do get some glassy conditions on Saturday morning, August 16th, with a 1.3ft SE swell, but it's just not enough to do anything with.
Honestly, with the persistent poor quality and onshore winds, if the wind cranks up, this setup might look more interesting for kite surfing than paddle surfing, but for us wave riders, it's a long wait.
Keep the board in the car, but don't hold your breath. Forecasts can change, but this blank run looks like the norm for now.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
